While caring for a client after a small bowel resection, the nurse is informed that the client has a history of methicillin-resistant Staphylococcus aureus (MRSA). To reduce the risk of recurrence of the MRSA in the postoperative wound, which intervention is most important for the nurse to implement?

A. Reporting an increase in the white blood cell count is important for monitoring infection but does not directly prevent recurrence of MRSA in the wound. B. Instructing the family to adhere to contact precautions is critical in preventing the transmission of MRSA and protecting the postoperative wound from infection. C. Changing the surgical dressing when soiled is important for wound care but is not as preventive as ensuring contact precautions are followed by all caregivers. D. Wearing a face mask while performing wound care is not a standard requirement for MRSA prevention in surgical wounds, as MRSA is primarily transmitted via contact.
